Slower than desired growth in crop yields coupled with rising food demand present ongoing challenges for food security in Africa. Some countries, such as Tanzania, have signed the Malabo and Abuja Declarations, which aim to boost food security through increasing crop productivity. The more intensive use of seed and fertilizer presents one approach to raising crop productivity. Our simulation study examined the productivity and economic effects of planting different seed cultivars and increasing fertilizer application rates at multiple spatial scales for maize in Tanzania.

Economists argue that land rent taxation is an ideal form of taxation as it causes no deadweight losses. Nevertheless, pure land rent taxation is rarely applied. This paper revisits the case of land taxation for developing countries. We first provide an up-to-date review on land taxation in development countries, including feasibility and implementation challenges. We then simulate land tax reforms for Rwanda, Peru, Nicaragua and Indonesia, based on household surveys.

Background: The Himalayan country of Bhutan is typically an agrarian country with about 57% of the people depending on agriculture. However, farming has been constrained by the mountainous topography and rapid changes in environmental variabilities. With climate change, agricultural production and food security is likely to face one of the biggest challenges of the twenty-first century.

Low productivity cattle ranching, with its linkages to rural poverty, deforestation and greenhouse gas (GHG) emissions, remains one of the largest sustainability challenges in Brazil and has impacts worldwide. There is a nearly universal call to intensify extensive beef cattle production systems to spare land for crop production and nature and to meet Brazil?s Intended Nationally Determined Contribution to reducing global climate change. However, different interventions aimed at the intensification of livestock systems in Brazil may involve substantial social and environmental tradeoffs.

El “huarango” (Prosopis pallida), es una especie vegetal que crece en las partes más secas a lo largo de la Costa del Pacífico y algunos sectores de la región andina del Perú, soportando un alto grado la deforestación debido a sus múltiples usos como alimento, forraje, abono, madera, medicinal, etc. Constituyéndose para el poblador rural en un recurso elemental para su desarrollo, aunque no siempre sea utiliza adecuadamente.

The global agricultural sector today faces the double challenge of feeding a growing population while preserving the underlying natural resources of land, water and air. In the meantime, already a third of the world’s soils are degraded. Soil and nutrient management techniques aimed at restoring soil health will therefore be essential to meeting these challenges.

The World Soil Day Photo book 2017 presents WSD photographic stories in a visual narrative. This publication recognizes and prizes the efforts of all WSD event organizers worldwide. On 5 December more people than ever celebrated soil, carbon, and the opportunities right under our feet under the slogan “Caring for the Planet starts from the Ground”. Healthy soils are the living, breathing ecosystems that help grow our food, clean our water, store carbon, and reduce risks of droughts and floods.

大约三年前，各国领导人就联合国《2030可持续发展议程》及其17个可持续发展目标达成一致，自此该议程和目标成为指导全球发展政策的核心框架。本版《世界森林状况》旨在加强我们对森林及其可持续经营如何为实现多项可持续发展目标做出贡献的理解。对世界森林而言，时间紧迫：我们必须开展跨部门协作，把利益相关方集合起来，尽快采取行动。《2018年世界森林状况》确定了可采取的行动，以增强森林和树木为加快实现可持续发展目标所必需做出的贡献。现在必须采取措施以更有效地与私有部门合作，必须对非正规部门进行改革，以实现更广泛的经济、社会和环境效益。七十年前，当联合国粮农组织完成其第一次世界森林资源评估的时候，主要关注在于是否有足够的木材来满足全球需求；而现在，我们则认识到森林和树木具有更为显著的全球意义。《2018年世界森林状况》第一次就森林和树木对景观和生计的贡献进行了评估。本报告目的是让更多读者了解森林和树木对人类、地球和子孙后代的重大意义。
